I created a standard catalog for deploying VM with ISO mounting (no VM template defined). I use this catalog in my advanced workflow, where I specify CPU, memory, disk size and ISO image. Whatever I configure in storage policy, the system disk is always created as thin provisioned. I do not want to use templates. Is there a way to force thick provisioning of primary disk? I can create additional disks as thick, but unable to force the system disk to be thick.
